Figure 7 is an end elevational view of the clip illus- Figure 8 is a vertical sectional view taken through a lower portion of the calendar during assembly thereof to illustrate the method of assembly.

While an illustrative embodiment of the invention is shown in the drawings and will be described in detail heretended use, the loose leaves forming the calendar pad tear loose from the binding, thereby rendering the calendar useless. Also, considerable difficulty has attended the assembly of the calendar parts, particularly where conventional expansible ring-type binders have been employed,

necessitating expensive, time-consuming labor in assembling the calendars.

An important object of the present invention is to provide a novel binding clip for the calendar parts which overcomes the disadvantages alluded to above in prior drop leaf calendars.

It is a more specific object of the invention to provide a new and improved calendar of the character described including a covering member folded at about its midportion down upon itself to form two panels including a backing panel and a front cover panel, a calendar pad in the form of a plurality of loose leaves adapted to be contained between the two panels on initial assembly of the calendar, and a novel clip for holding the calendar in assembled condition by hingedly or pivotally mounting the loose leaves to the backing panel adjacent its bottomedge so that the leaves may be dropped as desired,

in, the invention is susceptible of embodiment in many different forms, and it should be understood that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointed out in the appended claims. 1

Referring now to the drawings, as illustrated, the invention is embodied in a calendar comprised essentially of a covering member 10, a calendar pad in the form of a plurality of individual loose leaf drop pockets or envelops 13, and a binding clip 15 for retaining the calendar parts in assembled condition.

The covering 10, as illustrated, is formed from a single sheet of material which is folded down upon itself so f as to provide a rear backing panel 11 and an overlying, front cover panel 12. The panels 11 and 12 are thereby hingedly connected together at their upper edges so that the cover panel may be moved selectively between a first, closed position, as illustrated in Figures '1 and 2,

the clip and the front cover panel being formed with interfitting portions and the clip being adapted to receive a wherein individual leaves of the calendar pad are contained in concealed positions between the panels, and a second, open position providing access to the calendar leaves so that thetleaves may be dropped selectively to exposed positions, as illustrated in Figure 3. The rear backing panel 11 may be provided with an aperture, or both the panels 11 and 12 may be provided with aligned apertures, is illustrated at 16, to facilitate hanging the calendar on a peg extending from a vertically disposed wall surface.

While the backing panel 11 has been illustrated-as extending to a position slightly below the binding clip 15,

it will be appreciated that, if desired, the lower end of a the panel may extend further downwardly below the binding clip to form a backing for the drop pockets in their lowered position.

printed matter and pictures.

I cover panel completely conceals the leaves 13 which it pencil or the like which retains the cover panel in position against the calendar leaves.

Other objects and advantages will become readily apparent from the following detailed description taken in connection with accompanying drawings, in which:

Figure 1 is a front elevational view of a drop pocket calendar embodying the principles of the present inven-' tion;

Figure 2 is an end elevational view of the calendar as illustrated in Figure 1, taken from the left end of the calendar as viewed in Figure 1;

Figure 3 is an end elevational view similar to Figure 2, but with the front cover panel in raised position, and with an additional drop pocket shown in position to hang down below the front cover panel;

Figure 4 is a front elevational view of a lower fragretains in the upper position, this is not essential, and the cover panel may be reduced in size or other means may be provided to hold the leaves 13 in the upper position.

The individual loose leaves 13 forming the calendar pad may vary in number. Normally, however, the pad consists of twelve leaves corresponding to the twelve months in a year. The front of the individual leaves 13, as illustrated in Figure 1, are imprinted to represent the days and weeks of the months, and the rear of the indi- -vidual leaves, visible by turning the leaf upwardly, may

to be contained in concealed positions between the backmentary portion of the rear backing panel, illustrating in detail the slots provided in said panel;

Figure 5 is a front elevational view of an individual drop pocket, illustrating in detail the slots provided for p member, such as a pencil illustrated at 17 into the binding panel 11 and the cover panel 12. As described more in detail presently, the cover panel 12 may be clasped or retained in closed position by inserting an elongated ing clip 15. Upon removal of the pencil 17, the front cover panel 12 may be raised, as illustrated'in Figure 3, to expose the individual leaves 13 for movement selectively to a lower dropped position wherein the leaves A are exposed and hang down below the cover panel; Nor.-

Patnted Mar. 17, 1959 mally,. the leaves would be lowered successively at the beginning of the respective months in the year.

As illustrated, the individual loose leaves 13 forming the-calendarpad-each comprise an envelope or pocket open at the top front when the leaf is hanging down in the front panel 20. Pockets formed by the individual envelopes are thereby accessible when the individual leaf 13 is lowered to hang-down below the cover panel 12, and may be utilized during the month to retain bookkeeping :data such as bills and receipts. At the end of the yearwhen the calendar expires, the individual leaves may all be moved upwardlyto positions between the backing. and cover panels and the calendar filed away for record purposes.

While the invention has been illustrated in connection with a drop pocket calendar, it will be appreciated that it is by no means limited to such calendars, but that the leaves 13 may, if desired, comprise a simple sheet which isnot an envelope nor formed with a pocket.

In order to attach the binding clip 15 to the backing panel 11, the backing panel is formed adjacent its lower edge 11a (Fig. 4) with a first pair of spaced slots 24, and above the slots 24, with a second pair of slots 25. Midway between the slots 24 and 25, the backing panel 11 is prefolded or precreased transversely along the line 26 so that the lower edge 11a may thereby be turned forwardly and upwardly as desired. The function of the slots 24 and 25 and the crease 26 will be described more in detail presently.

In order to mount-the individual loose leaves 13, the rear panel 19 of each envelope is formed adjacent its lower edge 27 (when the envelope is positioned between the backing and 'cover panels) with a pair of spaced slots 28 (Fig. 5) of a size and shape similar to the slots 24=and 25 and spaced similarly. The function of the slots 28 will be described more in detail presently.

Referring now particularly to Figures 6 and 7, the binding clip 15 may consist of a plastic material and comprises a flat, narrow, elongated backing strip 30 adapted to underlie the rear backing panel. 11 when the calendar parts are assembled. The length of the strip 30 preferably is at least substantially one-third the width ofthe cover member 10 and the leaves 13, and is centrally located width-wise of the backing panel. The clip is ofrelatively rigid material, and the backing strip 30 thereby affords a support for the calendar parts. At one side of the backing strip 30, adjacent opposite ends of the strip, there are integral laterally extending hinge elements 31. The hinge elements 31, as illustrated, are arcuately curved and extend in a semi-circle from the backing strip, curving first forwardly and upwardly and then rearwardly and upwardly. Each of the hinge elements terminates in a narrow fiat end portion 32 which lies in the plane of the backing strip 30 and is parallel thereto. The hinge elements 31 each have a substantial width, relative to the length of the backing strip 30, and relative to the width of the backing panel 11 and leaves 13, so to provide adequate support for the calendar parts.

When'the calendar parts have been assembled, the backing strip 30 underlies the backing panel ll, the forwardly and upwardly curved portions 31a (Fig. 7) of th'e'hinge elements are received in the lower slots 24 in the-"backing panel; and the rearwardly and upwardly curved portions 31b of the hinge elements are received in the upper slots 25 ofthe backing panel. The end portions 32 of the hinge element's also underlie the backing pa'nel 11, and the curvedportions of the hinge 'eleportions project beyond the backing panel.

binding clip may then be pivoted downwardly with a ments overlie the backing panel between the slots 24 and 25 so that the clip is thereby attached to the backing panel 11. The curved portions of the hinge elements 31 also are received in the slots 28 of the individual leaves 13, so that the leaves are thereby hingedly mounted.

The front cover panel 12 is provided, adjacent its lower edge 12a, with a pair of apertures 33 (Fig. l) shaped and positioned to receive the curved portions 31 of the hinge elements when the cover panel is placed in the closed position illustrated in Figures 1 and 2. The apertures- 33 permit positioningof the cover panel in closely overlying relationship to the loose leaves 13 to conceal the leaves'which have not been dropped in a neat, tight package or pad between the. panels 11- and 12.. The cover panel 12 may then be latched or retained in this position, by inserting an elongated object, such as the pencil 17, overlying the cover panel, into the curved portions of the hinge elements 31. The pencil is thereby conveniently positioned for use with records to be kept in the drop pockets.

When the pencil is inserted into the curved portions oi the hinge elements 31, the fiat backing strip 30 and the flat end portions 32 are drawn forwardly against the rear face of the backing panel 11, to thereby tightly clasp the leaves 13 and panels '11 and 12 in a manner which permits extended use of the. exposed drop pocket without undue wear causing the pockets to tear loose from the binding.

Assembly of the calendar parts is effected by superposing the calendar leaves 13 over the backing panel 11 with the slots 28 in register with the slots 25. The lower edge 11a of the backing panel is turned forwardly and upwardly, bending the panel 11 along the crease line 26, so thatthe slots 24 overlie and register with the slots 28. If desired, the lower portion of the backing panel with the slots 24 may be turned upwardly before the leaves 13 are positioned or while the leaves 13 are being positioned so as to form a pocket into which the pad of leaves may be inserted. The slots 28 are spaced from the edges 27 by a distance substantially equal to the spacing of slots 24 and 25 from crease line 26. Thus, the slots 24, 28 and 25 may be positively aligned simply by inserting the pad of leaves into the pocket referred to with the edges 27 abutting the bottom of the pocket at the fold line 26. In Figure 8, the parts are positioned as described above.

With the parts thus positioned, the slots 24, 28 and 25 form registered openings into which the hinge elements 31 may be inserted. The insertion of the hinge elements into the openings is illustrated in Figure 8. Briefly, this comprises inserting the fiat end portions 32 into the openings. as illustrated in the full line showing of Figure 8. At this time, the leaves and panel are compressed into a relatively thin pad, if desired, by pressing the curved portions of the hinge elements against the upturned portion of. the backing panel, so that the end The entire rolling motion to the broken line position of Figure 8, wherein the end portions 32 underlie the backing panel. The upturned lower portion of the backing panel is then folded downwardly to overlie the backing strip, and the assembly is complete.
